High Temperature Shut-Off System
This water heater is equipped with an automatic gas Shut-off
system. This system works when high water temperatures
are present. Turn “OFF” the entire gas supply to the water
heater. The high temperature Shut-off is built into the gas control
valve. It is non-resettable. If the high temperature shut-off
activates, the gas control valve must be replaced. Call a Maytag
Service Specialist at 1-800-365-0024 for an authorized
servicer.
Leakage Checkpoints
Read this manual first. Then before checking the water heater
make sure the gas supply has been turned “OFF”, and never
turn the gas “ON” before the tank is completely full of water.
Never use this water heater unless it is completely filled with
water. To prevent damage to the tank, the tank must be filled
with water. Water must flow from the hot water faucet before
turning “ON” gas to the water heater, see Figure 28.
A. Water at the draft hood is water vapor which has condensed
out of the combustion products. This is caused by a problem
in the vent. Call a Maytag Service Specialist at
1-800-365-0024 for an authorized servicer.
B. *Condensation may be seen on pipes in humid weather or
pipe connections may be leaking.
C. *The anode rod fitting may be leaking.
D. Small amounts of water from temperature-pressure relief
valve may be due to thermal expansion or high water
pressure in your area.
E. *The temperature-pressure relief valve may be leaking at
the tank fitting.
F. Water from a drain valve may be due to the valve being
slightly opened.
G. *The drain valve may be leaking at the tank fitting.
H. Combustion products contain water vapor which can
condense on the cooler surfaces of the tank. Droplets form
and drip onto the burner or run on the floor. This is common
at the time of start-up after installation and when incoming
water is cold.
I. Water in the water heater bottom or on the floor may be from
condensation, loose connections, or the relief valve.
DO NOT replace the water heater until a full inspection of all
possible water sources is made and necessary corrective
steps taken.
Leakage from other appliances, water lines, or ground seepage
should also be checked.
* To check where threaded portion enters tank, insert cotton
swab between jacket opening and fitting. If cotton is wet,
follow “Draining” instructions in the Periodic Maintenance
section and then remove fitting. Put pipe dope or teflon tape
on the threads and replace. Then follow Filling the Water
Heater instructions in the Installing the New Water Heater
section.
